ATRAUMATIC EXTRACTION

A virtuous approach

ATRAUMATIC EXTRACTION vs TRADITIONAL EXTRACTION

Which are the key differences between the more classical way of extracting teeth and the atraumatic one? And why should you consider approaching this extraction technique?

A traditional tooth extraction implies the use of instruments in a prying motion (typically in a facial and lingual direction) to sever the periodontal ligament, and to expand the alveolus sufficiently to allow the forceps to pull the tooth and detach the remaining ligament fibers. The risks of this technique are the inadvertent pressure on an adjacent tooth, and the inadvertent fracture of the alveolar bone.

An atraumatic extraction is instead a technique developed to protect the bone of the alveolus and to protect the adjacent teeth. Using specialized instruments ( such as luxating elevators, periotomes, luxating hybrids and atraumatic forceps) the force applied to the tooth is directed apically, and the periodontal ligament is cut rather than torn.

ATRAUMATIC EXTRACTION IS NOT ONLY ABOUT ATRAUMAIR FORCEPS

Even though the most known instruments used to perform atraumatic extraction are probably the Hu-Friedy Atraumair Forceps, they represent just the cherry on top of a series of instruments which are crucial for a complete setup and procedure. Discover them all here below and of course do not forget about visiting the page dedicated to the Atraumair Forceps portfolio by clicking on the below button.

Luxating Elevators

Cut the periodontal ligament through an apical movement

A Luxating Elevator is a Straight Elevator design, with a thinner sharp working end. They are available in a range of widths (2mm-5mm) to accommodate the sizes of tooth roots. The difference in a Luxating Elevator compared to a standard Elevator is the mode of action when using the instrument. Luxation is the loosening of the tooth from the alveolar socket by severing of the periodontal ligament fibers.

The sharp working end of a Luxating Elevator is inserted vertically into the PDL with the tip closely adapted to the root surface and used with a rocking and cutting motion. The selection of a luxating elevator with a width that matches the root surface will enhance the adaptation.

Periotomes

For an easier access to the proximal surface

Periotomes are instruments used in an atraumatic extraction procedure. Although very different in shape and size compared to luxating elevators and hybrids, these instruments are also used to cut the periodontal ligament fibers. The blades are thin and sharp around the entire circumference of the blade, resembling a periodontal knife. This blade design allows deeper insertion subgingivally. This blade feature combined with the shank angles, permits better access to the proximal surfaces compared to a luxating elevator. Periotomes may be used with Luxating Elevators or hybrids or used alone to achieve the same goal of severing the periodontal ligament while minimizing damage to the alveolar bone during the extraction.

Luxating hybrids

To also cut the periodontal ligament through an apical movement, but with a smaller and ergonomic handle

The Luxating Hybrid design combines the style and functions of Standard Luxating elevators and Periotomes. The set of 7 single end designs offers a variety of straight and angled shanks, and large and small sizes, and all have thin sharp working ends/blades. These instruments are used apically within the periodontal ligament space to cut the PDL prior to tooth extraction. This method permits extraction without applying pressure on the alveolus, thus protecting the bone from fracture.
